Description

Half prefabricated prestressed concrete floor slab of figure of eight steel bar girder
Technical field
The utility model belongs to the floor technical field in building, and in particular to half prefabricated of figure of eight steel bar girder is pre- Prestressed concrete floor.
Background technology
The type of floor mainly has precast floor slab, cast-in-situ floor, composite deck slabs, steel bar girder at present Laminated floor slab etc. is several, although wherein prefabricated board speed of application is fast, flooring globality poor, poor rigidity, floor jointing processing are not Leading to later stage use well, there are leakage problems in the process, and due to flooring globality poor, when an earthquake occurs, earthquake is serious;It is existing Floor good integrity is poured, rigidity is big, stress is good, but wet construction of constructing is more(Reinforcing bar binding, formwork etc.), long in time limit, engineering cost High and the performance in its later stage and the maintenance of concrete have much relations;Although composite deck slabs eliminate cast-in-place The formwork of floor works, and speed of application is fast but deformation is big, costly, and the out-of-flatness of board bottom face, further needs exist for furred ceiling, this Bring expense;Steel bar girder prestressing force laminated floor slab overall stiffness is good, and speed of application is fast, but the steel using amount brought is big, expense It is high.
Utility model content
The purpose of this utility model is to provide half prefabricated prestressed concrete floor slabs of figure of eight steel bar girder, with solution It proposes that existing precast floor slab plate face is difficult in certainly above-mentioned background technology, and is suitble to span smaller, cast-in-situ floor is in work progress In, reinforcing bar binding work amount is big, steel bar girder prestressing force laminated floor slab steel using amount is big problem.
To achieve the above object, the utility model provides the following technical solutions:Half prefabricated of figure of eight steel bar girder is answered in advance Power concrete floor, including concrete on construction site layer and reinforcing bar, the concrete on construction site layer are located at prefabrication coagulation On soil layer, and the chord that winds up is disposed in prefabrication concrete layer, it is described to wind up positioned at the top of lower edge, the reinforcing bar difference It is welded to connect with lower edge and winding up, and lower edge and winds up and be located at the both sides of reinforcing bar, the lower edge winds up and reinforcing bar composition steel Muscle truss is disposed with fourth reinforcing bar vertical with steel bar girder in the prefabrication concrete layer.
Preferably, it the reinforcing bar and winds up and is both provided with folding foot with the weld of lower edge.
Preferably, the lower edge, wind up with the assembly of reinforcing bar be splayed structure.
Preferably, the 4th reinforcing bar is connect with steel bar truss welding.
Compared with prior art, the utility model has the beneficial effects that:
(1)The utility model is provided with prefabrication concrete layer, this preformed layer has certain rigidity and intensity, So temporary support need not be arranged in pouring at the scene, do not need formwork and may be used for floor slab construction, saves template, shortens Duration reduces expense, and has been set steel bar girder in prefabrication concrete layer, thus reduces reinforcing bar in constructing at the scene The workload of binding, shortens the duration, reduces cost;
(2)The utility model, construction site make concrete layer in steel bar girder be Penetrating wire for pipe provide very greatly Space, facilitate poling in work progress, and deformed bar, Neng Goushi are increased inside the concrete layer that makes of construction site It answers the requirement of large span floor while being suitble to the requirement of two-way slab.
